,To all whom if, may concern.' i,

Be it known that l, Heee HANS HERMANN von Finn, a citizen of the United States of Venezuela, and resident of Hainbur Germany, have invented a nevv and useil Device for Carbonatine; Liquids, of which the following is a specication.

The device forming the subject matter of this invention is a carbonating device of such kind, in which there. is a mixingif ves.- sel, into the upper partei which the iquid to be impregnated and also the gas is led, so that merely that quantity, which is to be tapped or given oil is mixed or impregnated.

lt has been found out, thatlhe impregnated liquid will have a perfectly pure taste, when the nir contained in the mixing vessel and the air accompanying the liquid is pelled as soon as the gas and the liquid nre introduced and when care is taken to avoid the sir from coming in contact with the irnpregnated liquid. This is arrived at by arranging above the mixing;I vessel and separate from itan air reservoir, which is connected with the mixing vessel merely by e narrow channel and provided with a nonreturn valve and With an air escape valve.

ylihe air gathers in the upper part. of the vessel on account of its beinglighter than the liquid and therefore can easily be let` @if into the air reservoir, the narrow chanexpelled nir from coming into contact with the impregnated licluid. rlhe non-return valve prevents the-air Irom flowing back into the mixing vessel.v The air escape valve is adjusted to the seme pressure as or to a somewhat higher pressure than the pressure of the intlowing gas, so that air escapes, when there is pressure owing to an abundant delivery or passage of air.

ln the drawing Figure l isan elevation partly in section of a tapping device to carry outy this invention by way of example. Fig. shows the tankfor receiving the'expelled air in sectional elevation to a larger scale.

The tank or container a, into which the liquid is filled, is closed and 'provided with an upright inner tube l), to which is connected the outer tube o, leading to the upper pnrt oi' the mixing' vessel I through an atomizer (I, the lower part ot' the miving vessel which is preferably ol' glass is provided with a lapping' cock. The gas (such as carbonic scid) used to expel the liquid from the an excess of .ges to the vessel above, the liquid container c into the vessel a7, and to impregnato the same in the letter, is contained in a flask f and led into the container c by the pipe g and into the vessela by the pipe fr. ly the aid oi' pressure reducing valves g', fr' the pressure in the pipe Ill will be reduced to somewhat less than thepressure in the pipe g to allow the liquid 'to be driven from the container a inte the vessel d filled With gas.

Outside and above the vessel nl a chamber or tank z' is provided for gathering. the nir This tank z' .is connected with the vessel d by a pipe l and paage n and is provided with a non-return valve m and air escape valve m1. 'The pie h connects the pipe F, with the flask f. "lihe/passege n, which leads from the pipe Z to the inside ci the vessel d is very narrow.

From the description given shove' it will be seen that gas een always ireely enter the vessel d. The valve or cock k' of the 'pipes' is opened, whereby liquid can ente-r the ves- .sel d, at the same time being Well itemized by the nozzle or atomizer c. This basut'he ellect, that the liquid is well spread and easily and abundantly saturated with gas, the atmospheric air being 'expelled and driven `by Way of the nerrow channel or passage ny into 'the tank 1', from where it can escape through the air valve m1.

lil desired the liquid may be derived -from a pressure pipe or common Water main pipe, in which case the container a sind pipe g may be dispensed with.

claim:

A device for carbonating li nids comprising a. mixing. vessel, anair member, a channel connecting the upper part of the vessel With the chamber, a pipe for conducting i liquidto the upper part oit the vessel, a4 pinel for conducting gas to the vessel shove li uid andcommunicet-ing with the nir' chem er, and an air escape valve in the latter.

2. A devicefor cerboniitingg liquids comprisinga mixing vessel, an sir chamber, a narrow channel connect-ing; the lower part. of the chamber with the upper part of the vessel, a pipe for conducting liquid to the npper part of the latter, a, pipe for condueiingj and ceinmnnicating with the air chamber, sind en air escape valve in the latter.

3. A device for carbonating liquids com- -prising a mixing vessel, on air chamber, s
